A certain half-reaction has a standard reduction potential
=E0red−0.99V
. An engineer proposes using this half-reaction at the cathode of a galvanic cell that must provide at least
1.20V
of electrical power. The cell will operate under standard conditions.
Note for advanced students: assume the engineer
requires this half-reaction to happen at the cathode of
the cell.
Is there a minimum standard reduction potential that the
half-reaction used at the anode of this cell can have? If so, check
the "yes" box and calculate the minimum. Round your answer to 2
decimal places. If there is no lower limit, check the "no" box.
yes, there is a minimum. =E0red V no minimum Is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box.yes, there is a maximum. =E0red V no maximum By using the information in the ALEKS Data tab, write a balanced equation describing a half reaction that could be used at the anode of this cell.

We will answer these questions based on the equation,
Eocell = Eocathode - Eoanode
1. No , there is no minimum standard reduction potential that the half-reaction used at the anode of this cell can have.
We need a minimum cell potential of 1.20 V.
Given, Eocathode = -0.99 V
Therefore,
Eocell = Eocathode - Eoanode
1.20 V = -0.99 V - Eoanode
Eoanode = -2.19 V
The reduction potential of anode should be -2.19 V or lesser to obtain the required cell potential .
2. Yes, there is a maximum standard reduction potential that the half-reaction used at the anode of this cell can have.
From the calculations done in previous part, the maximum standard reduction potential of anode must be -2.19 V.
If the standard reduction potential that the half-reaction used at the anode is more than -2.19 V, we will nor be able to derive the minimum required potential of 1.20 V.
3. At anode, the electrode process that happens is oxidation.
The balanced equation describing a half reaction that could be used at the anode of this celi is
Ca (s) Ca 2+(aq) + 2e-
The standard reduction potential for this half cell is Eo red = -2.868 V
